1-. In the manufacture of pin tumbler cylinders, castings of difierentslze and shape are usually made to fitvarying types of locks andinstallations, for instance, a pin tumbler cylinder may be installed ina door knob or 10 it may be installed in an auxiliary lock such as anight latch or the like. In each installation diiierent conditions areencountered and change in the shape and size of the casting isaccordingly necessary in all installations. The pin tumbler cylindershould be made readily removable and interchangeable for repairs andalso to permit changing of the combination and the cylinder must berigidly supported when installed.

provide a mounting or housing for pin tumbler cylinders of the characterdescribed which permits the use of a standardized pin tumbler cylinder;to provide a housing'in 25 the form of a cylinder or shell which may bepressed or formed from sheet metal or the like; to provide ajhousi'ngwhich is readily adaptable for installation in varying sizes and formsof locks; to provide a housing which permits ready insertion or removalof a pin tumbler cylinder; to provide a housf ing in which. the pintumbler cylinder'may be rigidly supported and secured; to provide ahousing which permits insertion of stand ardized 'pin tumbler cylindersof varying lengths, for instance, cylinders containing four, five ormore pin tumblers; and further, to provide a housing which may bereadily anchored, connected or secured with relation to a door or themechanism to be actuated thereby.

A standardized form ofpin tumbler cylinder together with thehousingprovided for its reception is shown by way of illustration in theaccompanying drawing,in which Fig. 1 is a perspective View of astandardized form of pin tumbler cylinder,

Referring to the drawing in detail and particularly Figs. 2 to 6,inclusive, A indicates a cylindrical shaped housing provided with anintegral bottom or'end section B at one end and an outwardly turnedannular flange C at the opposite end. The housing is prefs erably formedof sheet metal or the like and as such may be stamped, pressed, orotherwise formed. The housing is designed for the reception and supportof a pin tumbler cylinder such as shown in Fig. 1. This pin tumblercylinder consists of a cylinder or body-portion 2 which is provided witha plate like .extensiOnB. The cylinder body 2 and the extension 3encl0se a plug and pins or tum blers of the usual construction and theplug is secured against endwise removal by an end plate or cam-4', theend opposite to the cam or plate 4 indicated at 5 being the end throngwhich the key is inserted.

The type of pin tumbler cylinder shown in Fig. l is being manufacturedby applicant and it .may contain three, four, five, or more pin tumblersas the case may be so as to obtain numerous combinations. All pintumbler cylinders are uniform in diameterand the dimension of theextension shown at 3 is maintained uniform, hence all pin tumblercylinders are standardlzed as far as cross sectional shape is concernedbut they may be increased or decreased in length in proportion to thenumber of pin tumblers provided.

The housing indicated at A is particularly designed for the receptionand support of a standardized type of pin tumbler lock such as shown inFig. 1. The bottom or inner end of the housing is accordingly providedwith a round opening 2a to receive the body 2 of the pin tumblercylinder and the bottom is also at 7 in Fig. 6. The face plate, togetherwith the reinforcing plate 6, is provided with a round opening such asshown at 8, this opening being provided for the reception of the frontor key end 5 of the pin tumbler cylinder when it is inserted in thehousing. The openings-Qa and 8 formed at the respective ends of thehousing form seats and supports for the pin tumbler cylinder while theradially extending slot 3a receives the body extension 3 of the pintumbler cylinder. This slot'engages the sides of the extension 3 and assuch secures the pin tumbler cylinder against rotation when supported inthe seats provided by the openings 2a and 8.

Means must also be'provided for'securing the pin tumbler cylinderagainst endwise removal when inserted in the housing. This isaccomplished by providing a U-shaped clip 9 such as shown in Figs. 2, 4,and 5; The clip isprovided with a pair of outwardly extending lugs 10and the slot 3a is cut away as shown at 3?) to receive the lugs 10 ofthe clip. The clip when applied straddles the inner end of the bodyextension 3 and the lugs '10 pass through the enlarged portions 36 ofthe slot 3a. The clip isthen pushed inwardly towards the body portion 2of the pin tumbler cylinder and as such passes in underlugs 10?) formedby the bottom section of the housing at a point just below the enlargedportions 36 of the slot. The clip'when thus applied secures the pintumbler cylinder against endwise removal and it may here be stated thatclips of varying length are provided. In the present instance afive pintumbler cylinder lock is shown. A five pin tumbler cylinderv lockextends a short dis tance beyond the bottom end B ofthe housing and thelegs of the clip are accordingly made of a length which will juststraddle the end of the cylinder body and thereby secure it withrelation to the housing. If a four pin tumbler cylinder lock is employedthe distance the end of the pin tumbler cyl- The forward end of inderprojects will be proportionately de creased and a shorter clip such asshown in Fig. 2 will be employed. On the other hand if a six pin tumblercylinder lock is employed it will project a greater distance as shown inFigs. 4 and 5 and a clip with longer legs will be employed.

From the foregoing it should be clear: First, that a housing constructedas here shown is capable of receiving a standardized type of pin tumblercylinder lock such as shown in Fig. 1; Secondly, it will be noted thatpin tumbler cylinder locks of varying lengths may be inserted; Third, bymerely removing the clip 9 the cylinder lock may be quickly and easilyremoved for inspection, repair, change, or otherwise, and a new pintumbler cylinder may just as easily be inserted, hence it is asimplematter to change the combination in a lock provided with a housingor mounting such as here shown.

The present application illustrates two methods of connecting thehousing A with relation to the latch or bolt mechanism of a lock. InFig. 9, the housing A is shown as having a thread formed on the exteriorthereof as indicated at 12. The housing A may thus be screwed into thehousin D of a mortise type of lock and it may theredoe secured by ascrew or look such as indicated at 13.

In Fig. 8 another form of anchorage or securing means is shown. In thisinstance the housing A isprovided with apair of posts such as shown at14. These may be riveted or-otherwise secured to the bottom end B of thehousing and the outer ends are preferably drilled and threaded as shownat 15. The posts 14:, as shown in Fig. 8, pass through an anchor plate16 and in this manner secure the bolt housing 17 against removal, thehousing A, together with the post 14:, being in turn secured againstendwise removal by screws 18 which pass through an escutcheon plate 19and which enter the threaded ends of the post. Such a connection, by theway, is also adjustable as the posts may be shortened or lengthened orthe screws 18 may be shortened or lengthened thus taking care of doorsof different thickness. The lock housing is accordingly adapted forready installation and connection with locks of different types andsizes and when so attached is rigidly secured against removal; the housing A being provided with means either in the form of posts 14 or ascrew thread connection 12 whereby it may be connected and secured withrelation to other lock mechanisms or mechanisms actuated thereby; andfurthermore being provided with means for retaining, supporting andsecuring a pin tumbler cylinder.

The housing is simple and substantial in construction and it is cheap tomanufacture as it may be stamped, pressed, or otherwise formed, and asthe outer face thereof may be reinforced with an inner plate such asshown at 6 a rather cheap or inexpensive face plate 7 may be employed.

While certain features of the'present invention are more or lessspecifically described, I wish it understood that various changes may beresorted to within the scope of the appended claims. Similarly, that thematerials and finishes of the several parts employed may be such as themanufacturer may decide, or varying conditions or uses may demand.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A pin tumbler cylinder lock mounting comprising acylindrical shaped elongated housing, an integral bottom member on thehousing, said bottom member having an opening formed therein conformingto the cross sectional shape of the pin tumbler cylinder lock, a faceplate secured to the opposite end of the housing and having an openingformed therein to receive the key end of the pin tumbler cylinder lock,said bottom and face plate openings permitting endwise insertion of apin tumbler cylinder lock, a'U-shaped clip adapted to straddle the innerend of a pin tumbler cylinder when inserted in the housing, and lugs ontheclip engageable with the bottom member of the housing to secure thepin tumbler cylinder lock against endwise removal from the housing.

2. A pin tumbler cylinder lock mounting comprising a. housing havingopenings formed at opposite ends through which a pin tumbler cylinderlock is insertable, means engaging one end of the housing and theadjacent end of the pin tumbler cylinder lock to secure the pin tumblercylinder lock against endwise removal with relation to the housing, anda pair of posts carried by the housing whereby it is adapted to besecured with relation to a mechanism actuated by the pin tumblercylinder lock.

3. A structure of the character described comprising a cylindricalshaped housing having an integral bottom member, said housing being openat the opposite end and provided with an annular flange, a face plateadapted to be secured to said flange, and a pair 7 of posts secured tothe bottom member;
